Hello there,

Well it tells you the issue. There seems to be a column called "ms_wic_addon_permissions" in your table "usergroup" in the database. But this column is not registered. Do you still have installed the plugin that created this column in the table? Some plugins don't drop their database activities even when uninstalling.

If not you can try to delete it via your Database Manager (phpmyadmin or so.)
You can do this manually or use a SQL command, that might look like this:

ALTER TABLE 'usergroup' DROP COLUMN 'ms_wic_addon_permissions';

Please keep in mind that this command will delete the whole column from the table and it is not possible to undelete it again, except you're using a backup file.
